SHOE-JACK.

Specification of Letters Patent.

Patented Sept. 3, 1912 To all whom it may concern Be it known that I,Gnome W. HARRISON, of Indianapolis, county of Marion, and State ofIndiana, have invented a certain useful Shoe-Jack; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings. L

The object of th's inventionis to improve the construction of shoe jacksso as to facilitate their operation and use.

The nature of the. invention will be understood froin the accompanyingdrawings and the following description and claims.

In the drawings, Figure 1 is'a side elevation of the jack in its uprightposition. Fig. 2 is a central vertical section through what is shown inFig. 1, showing the device in its idle position and with theshoe-holding arm partly broken away. Fig. 3 is the same as Fig. 2,showing the parts in their operative position. Fig. 4 is a perspectiveview of the means for mounting the shoeclamping arm. Fig. 5 is atransverse section through the device on the line 5-5 of Fig. 1. Fig. 6is a side elevation of the middle portion of the device with the upperpart of the column tilted and the upper part of the tilted portionbroken away as well as part of the base.

There is shown herein a base 10 with an annular opening in the upper endand into which the lower member 11 of the tubular stand or last supportprojects loosely. Said portion 11 has an annular flange or shoulder 12,which rests upon the base, and the arrangement is such that the lastsupport can be turned or oscillated on its base. The base also has avertical opening or slot 13 through which thepedal lever 14 extends, andsaid pedal lever is pivoted at one end on the pin 15 in the base.

The last is supported by an upper tubular supporting-member .21, whichis hinged at its lower end by the hinge 22 to the upper end of the lowermember ll of the last support, so that the upper end of the jack may betilted or turned on its hinge until it is stopped by the stop-arm 23.Said stop-arm is adjustably secured to the lower tubular member 11 ofthe last-support, so it can be adjusted vertically and thus the angularposition of the upper part of the jack, when it is tilted, can bepredetermined. This vertical adjustment of the stop 23, as

herein shown, consists merely of set-screws or bolts 24 extendingthrough a vertical slot 25 in the lower part of the stop.

The last 20 has a cylindrical lower end or shank 26 which fits into thetubular upper end of the portion 21 of the last-support and is providedwith shoulders 27 which rest upon theupper end of said tube 21. There isalso a band 28 surrounding the upper end of the tubular support 21 andon one side it hasa beveled projection or lug 29.

There is a shoe-clamping arm 30 which is pivoted at its lower end to anarm 31 of a plate 32, which is vertically movable or slidable in theupper tubular member of the last-support. Said plate 32 is cylindricalexcepting that at one side it has the arm31 projecting from it through avertical slot 33 in the member 21 of the last-support. An eye-bolt 34 issecured to and extends down from the plate 32 and to it a cable 35 issecured. This cable extends down through the tubular support 21, passingabout a roller 36 mounted in the lower part of said support 21 and thenextending outwardly through a vertical slot 37 in the rear side of thelower end of the support 21 and about a roller 38 which is in alinementwith the joint between the sections of the hinge22, and from that thecable 35 extends through a vertical opening or slot 39 in the rear sideof the upper end of the lower tubular support 11 and over a roller 40anddown to a connection with the pedal lever 14 between its ends. Theplate 32 is supported by the spring 41 lying in the tubular support 21and resting upon an annular inwardly extending flange 42 from the lowerportion of said tubular member 21.

The upper end of the arm 30 is curved so as to be movable and extendover the last, as shown in Fig. 3,-and, therefore, over a shoe placedupon the last, so that when said arm 30 is drawn down the hooked upperend thereof will hold and bind the shoe upon the last. Said hooked armis drawn down and helddown by the pedal 14, cable 35 and plate 32. Byextending the .cable 35 outside of the tubular supporting members 11 and21, and passing it over a roller in alinement with the middle of thehinge 22, the action of the pedal 14 and,

of the jack, and, therefore, can be utilized whether the same be uprightor tilted. The ower part of the arm 30 has a beveled lug 43 in positionto engage the beveled lug 29 on the band 28, when the pedal is released,and the spring a1 forces the plate 32 and hooked arm 30 upwardly, afterthe shoe has been treated, and thus automatically throws the hooked armofi the shoe and last. It is thus seen that said last is easilyoperated. lVhen the pedal is released, the shoeclamping arm is thrown01f the shoe automatically, and after the shoe has been placed on thelast, said hooked arm is moved by hand in position to engage the shoe,and then the pedal is depressed, whereby the hooked arm will hold theshoe on the last. Also, the upper part of the last-support can be tiltedso as to bring the shoe in a desired position for treatment, and thistilting can take place without interfering with the operation of theshoe-clamping hooked arm, for that can be operated by the pedal whetherthe last-support is upright or tilted.

I claim as my invention:

1. The combination with a last, of a support therefor, a shoe-clampingmeans, a spring support operably connected thereto, means for depressingthe same for clamping the shoe on the last, and means for causing thedisengagement of said shoe-clamping means from the shoe when saidclamping means is released and actuated by said spring support.

:2. The combination with a last, of a sup port therefor, a platevertically movable below said support, a hooked arm pivoted at its lowerend to said plate wit-h its upper end adapted to be projected over thelast, a spring for supporting said plate in an elevated position, meansfor depressing said plate for holding said hooked arm on the last,inclined lugs on said support and said hooked arm adapted to engage eachother as the hooked arm rises after said plate is released and force thehooked arm away from the last.

3. The combination with a last, of a tubular support slotted verticallyat one side, a plate vertically movable in said support with aprojection extending out through said slot, a hooked arm pivoted to saidpro- 'jection with the upper end adapted to extend over the last, aspring in said tubular support for forcing said plate upward, means fordepressing said plate, a band around the upper end of said support witha beveled lug thereon near the hooked arm, and a lug on the lower end ofsaid arm adapted to engage said first-mentioned lug when the spring actsto force said plate upwardly and thereby throw the hooked arm away fromthe last.

4. The combination with the last, of a tubular support therefor, ashoe-clamping means, a spring support operably connected thereto, alever near the lower end of said tubular support, a cable extending downthrough said spring support and the lower end of said tubular supportand connected with said lever between its ends, whereby saidshoe-clamping means may be depressed for clamping the shoe on the last.

5. The combination with a last, of a support therefor consisting of twomembers one above the other and the two hinged to gether at theiradjacent ends so that the upper member and last can be tilted,shoeclamping means movable in the upper lastholding member, a spring forforcing said shoe-clamping member upward, and means operable throughsaid last-supporting members for depressing said shoe-clamping member.

6. The combination with a last, of a support including two tubularmembers hinged together at their adjacent ends and provided near saidhinge with openings therethrough so that the upper member and last canbe tilted, shoe-clamping means vertically slidable in the upper member,a yielding means for supporting said shoe-clamping means in its elevatedposition, rollers in the adjacent ends of said supports, a roller at themiddle of said hinge, a pedal in the lower part of the device, and acable extending from said shoe-clamping means over said rollers andthrough said openings and connected with said pedal, whereby theshoeolamping means can be held down or oper ated While the last istilted or upright.

In witness whereof, I have hereunto affixed my signature in the presenceof the witnesses herein named.
